  • Method for hierarchical cluster voting in a cluster spreading more than one site
    Patent number: 9015518
    Abstract: Resources may be assigned to nodes within a cluster of nodes and the nodes grouped to form sites. Each of the sites may elect a primary node to handle communications between the site and other sites within the cluster. The primary node of a site may be selected by a node identification number assigned to the node. When a node disconnects from a site, the node may form a temporary site and attempt to reestablish communications with the cluster. If communications are restored with the original site, then the node may rejoin the site. If communications with other sites are restored, then the node may form a new site. The dynamic cluster is tolerant to faults and failures within the nodes, because the nodes have information regarding the entire cluster. A site may remain operational with as few as one remaining node.
